Abstract

Abstract The crystallographic and magnetic structures of Nd₂Fe₁₇N_x(x = 2.5, 3.0, 5.5) at room temperature were refined by Rietveld analysis of neutron powder diffraction data. We found that Nd₂Fe₁₇N_x has a Th₂Zn₁₇ type structure (S.G. R3m) and the nitrogen atoms occupy both 9e and 18g sites simultaneously and at different rates.
